[Regan_tyler]

Can anyone tell me what this black algea type stuff is and how to get rid of it? Thank you

looks liek cyanobacteria

Yup, cyno. Usually caused by low flow, over feeding, too much light

Water changes, reducing feedings, shortening the photo period. Cyano runs on nutrients and light. it';s not caused by low flow however. I've seen it in the outputs of power heads and no where else.

What do you mean photo period?

The amount of time your lights are on.
